WebConvection also plays a role in the movement of deep ocean waters and contributes to oceanic currents. Inside Earth, the convection of mantle material is thought to cause the movement of the overriding crustal plates, resulting in events such as earthquakes and volcanic eruptions.

How does convection current occur in the mantle of the Earth?

WebConclusion. Drought can be triggered by physical conditions such as lack of rainfall, high temperatures, and low humidity. These factors can lead to soil moisture depletion and reduced water availability for plants and animals. Human activities such as deforestation and overuse of groundwater resources can also exacerbate drought conditions. WebConvection is the exchange of heat energy by the development of a liquid (fluid or gas) between regions of various temperatures. Warm air is less thick than cold air, thus convection flows are created within the sight of a temperature angle. At the point when flows are created distinctly by temperature-inferred density contrasts in the liquid ... darwin racisme

"WebThis occurs above rising convection currents. The rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it. This lateral flow causes the plate material above to be dragged along in the direction of flow. At the crest of the uplift, the overlying plate is stretched thin, breaks and pulls apart.
